When chest sleeping isn’t working anymore

Baby boy is 4.5 months and we’ve chest slept since day 1. He has really bad reflux and body tension/muscle tightness so it’s been the only way he can sleep. He slept great the first few months buuttt he’s sleeping terribly now. He seems really uncomfortable on me and wakes often. He’s also a pretty big guy and I’m pretty small so I wonder if he’s just outgrowing me. Anyways, any tips on how to get him to sleep now? I try putting him on his side next to me (he absolutely won’t sleep on his back) but he’ll wake after 30 minutes. I don’t feel comfortable having him sleep on his stomach in my bed but he’s never slept away from me and the few times I did try the bassinet it was a fail. via /r/cosleeping https://ift.tt/RjxIG2c
